概要
Spec-Driven Development (SDD) is a standalone methodology designed for Claude Code that enforces a structured workflow starting with detailed specifications. By separating the 'what' and 'why' from the 'how,' it ensures that features are well-defined before implementation begins. The skill automatically manages a dedicated directory structure to store specifications, technical plans, and task lists, providing a clear audit trail and reducing errors during complex feature development or greenfield projects. It effectively bridges the gap between high-level ideas and executable code through a disciplined, phase-based approach.
